With the volume of space junk reaching the 7000-tonne mark, space junk has now become a serious concern for #spaceagencies like #NASA, #ESA, and #ISRO. It has also been suggested that at a certain stage the sheer volume of space junk will trigger a cascade of collisions which would render an orbit unusable. Space organizations like NASA say that #avoidingcollisionofspacedebris is easier said than done; there are far too many parameters which affect an orbiting piece of space junk.

Earlier this year, the Chinese have proposed another laser-based approach of dealing with space debris; their solution included using #satellitemountedlasers to nudge the orbiting space debris into a lower orbit.
